Information processing with a chemical reaction-diffusion medium

I am going to give a short presentation on the information processing functions that can be executed by a reaction-diffusion medium. Different methods of information coding that can be adapted will be discussed. Within a particular assumption on information coding some algorithms like image processing, labyrinth solving or specific geometrical transformations, are automatically executed by the medium. The number of information processing operations increases if the medium is non-homogeneous and composed of parts characterized by different excitability levels. Using such medium one can easily build signal diodes, logic gates or memory cells. There are specific geometrical structures, such that the function they perform can be programmed with excitation pulses. I will also discuss the problems of functional scalability of chemical medium and of universality of its computing functions. Finally, I will present the perspectives of the field and put some questions that can be important for the further progress.
